            public void lambda() {
                System.out.println("I like Lambda4");
            }

        like.lambda();

        //6、用Lambda简化
        like = ()-> {
            System.out.println("I like Lambda5");
        };
        like.lambda();
    }
}

//1、定义一个函数式接口
interface ILike {
    void lambda();
}

//2、实现类
class Like implements ILike {
    @Override
    public void lambda() {
        System.out.println("I like Lambda");
    }
}
